摘要
观测了百合属植物的萌芽期、展叶始期、现蕾期、花蕾变色期、初花期、盛花期、果熟期和枯萎期出现的时间,并对观测结果进行相关分析和主成分分析。结果表明:各种源的物候期存在较大差异,其中以初花期差异最大,展叶始期差异最小;各种源生长期长短的主要影响因素是生长后期各物候的差异程度;伴随着萌发期和展叶始期的提前,现蕾期、花蕾变色期、初花期和盛花期出现的时间会延后,即过于追求百合的营养生长,会使其生殖生长延后。
Observed germinating stage,the stage of leaves beginning unfolding,visibling bud stage,buding allochromasia stage,initial flowering stage,full flowering stage,fruiting stage,withering stage of plants,and writed the time of appearance,use the method of correlation analysis,principal component analysis and systematic cluster analysis observed result The results showed that there were big differences in phenophase among these material,the anthesis stage was most obvious,the stage with minimum difference was leaves beginning unfolding.Different germplasm had difference growth period,and its main influencing factor was the difference of each phenological phases.Along with germinating stage and the stage of leaves beginning unfolding in advance,visibling bud stage,buding allochromasia stage,initial flowering stage and full flowering stage will be later.Means too pursuit vegetative growth,would cause its reproductive growth delayed.
